Description
【発明の詳細な説明】 <産業上の利用分野> 本発明は、モノコック構造による車両用フロアパネル
構造に関するものである。The present invention relates to a vehicle floor panel structure having a monocoque structure.
<従来の技術> 鋼板パネルの溶接組立によるモノコック構造の車体の

般的である。<Prior Art> In the case of a vehicle body having a monocoque structure formed by welding and assembling steel sheet panels, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 60-44874, the vehicle body extends in the front-rear direction in the central portion of the floor plate of the passenger compartment. It is common to obtain the main rigidity of the chassis by a floor tunnel having a concave lower surface and a cross member having a hollow closed cross section that extends in the left-right direction below the rear seat.
一方、前輪駆動車の場合、フロアトンネルの内側には

ルが接続される部分には、フロアトンネルの下面と連続
する凹部が形成される。そのため、クロスメンバの断面
積が、車幅方向の中央部で縮減することが通例であった
(上記公報の第1図参照)。On the other hand, in the case of a front-wheel drive vehicle, since the exhaust pipe extends inside the floor tunnel, a recess that is continuous with the lower surface of the floor tunnel is formed in the portion of the cross member where the floor tunnel is connected. Therefore, it has been customary that the cross-sectional area of the cross member is reduced at the central portion in the vehicle width direction (see FIG. 1 of the above publication).
ところで、プロペラシャフトを必要としない前輪駆動
車の場合は、フロアトンネルは比較的偏平で良く、フロ
アトンネルが食い込むことによるクロスメンバの中央部
の断面積の縮減は比較的少なくて済むことから、同部分
の剛性低下は殆ど問題にはならなかった。By the way, in the case of a front-wheel drive vehicle that does not require a propeller shaft, the floor tunnel may be relatively flat, and the reduction of the cross-sectional area of the central portion of the cross member due to the biting of the floor tunnel is relatively small. The decrease in rigidity of the part did not pose a problem.

など、居住性を損う不都合が生ずる。<Problems to be Solved by the Invention> However, in a vehicle such as a four-wheel steering vehicle in which front and rear axles are mechanically connected, a link rod or the like for transmitting steering force to the rear wheels is not provided. Since it must be installed in the floor tunnel together with the exhaust pipe, the height dimension of the floor tunnel must be as large as that of a rear-wheel drive vehicle. Therefore, in order to secure the cross-sectional area of the portion of the cross member that intersects with the floor tunnel, the height dimension of the cross member must be increased, and the seat seat surface becomes high, which causes inconvenience to impair comfortability. .
